        <footnote id="F1">Represents 1,152 shares of common stock underlying restricted stock units (&quot;RSUs&quot;) granted to the reporting person under the issuer's Long-Term Incentive Plan. Each RSU entitles the reporting person to receive one share of common stock upon vesting of the RSU. The RSUs will vest in three annual successive installment upon the completion of the reporting person's completion of each year of services with the issuer for the three-year period measured from the date of grant, subject to accelerated vesting under certain prescribed circumstances.</footnote>
        <footnote id="F2">Represents 2,972 shares of the issuer's common stock and 4,283 shares of the issuer's common stock underlying RSUs that will vest and become issuable in accordance with their terms.</footnote>

The issuable shares were previously reported as Table I securities in the Form 3 filed on April 30, 2015, and accordingly the issuance of those shares is not a reportable transaction on this Form 4.</footnote>
